It can seem tricky to integrate ln(x), as there is no obvious solution to do it.It is, however, quite simple to do if you use the 'by parts' method.If you have y=ln(x)Set u=ln(x) and dv/dx=1That gives du/...
Stationary point: dy/dx = 2e^2x - 11e^x =0 2e^2x = 11e^xe^x=5.5 (can divide by e^x since e^x > 0 for all x)x=ln(5.5), y=5.5^2-115.5+24=-6.25Answer: AJAnswered by Asmita J. • Maths tutor2874 Views
Put simply, mutually exclusive events cannot occur at the same time, e.g when tossing a coin, the result can either be heads or tails but cannot be both. Independence of events means the occurrence of one...
When differentiating an equation (y) you find the equation of the gradient, called dy/dx. The rule for differentiating a power of x is given below:y=x^n dy/dx= nx^(n-1)Applying this rule to this question ...
